parts spaced above each other, and these four The bottoms are made of several plates indouble links are crosslaid in such manner that terconnected lay-hinges, and are connected to 100 At the end corners of the carriageV are` journalled rods 60, 61, turnable about a ver tical axis and carrying the handle parts 63',- 64, which may be interconnected by aid ofY a screw part 66, adapted to be screwed into` f .a socket'in the other part of the handle. These handle parts are journalled on lugs 67, attached to the ends of' the rods 60, 61.

- For the purpose of keeping these arms in position, they are provided with lugs 68, 69, engaging the journals 70. When the interconnection between the handle part-s 63, 64` is severed,"the arms 60, 61 may be swung backy as indicated `in broken lines in Fig. 1,

and the handle parts may again be interconnected in this position and may then serve to prevent the child from comingout of the fcarriage, to suspend playthings in, or the like.l The carriage is provided with a hood or top, having two-part ribs7 5, hinged at 76, soas to fold together, when the carirage' is folded or `collapsed (Fig. 6). VThe free ends ofthe ribs are turnably mounted in sleeves 77, having horizontal piv- `ots 78 journalled in mountings 79, which lare '.attachably fastened to the edge of the side walls of the carriage. The lowermost'rib is in its front end provided with adepending lug 80, havinga boring, with which engages a tooth 81 on a spring82, fastened to theinner side of the `front wall.` This spring may be disengaged'by pressing a button 84, -protrading through a boringin the front wall and fastened to the spring 82 in such inanner that the pressure on the spring releases the tooth 81 from the lug 80 ofthe rib, whereupon this rib, is lifted by a Vspring actuated lug 85 mounted on the inside ofthe front wall,l thereby bending all of the ribs about their hinges. When pressure is exerted against the side walls of the carriage for the purpose of folding Vit up, the ribs will automatically be bent further about their top hinges (Fig. 6). rlheribs are lockedin-position for use in the usual manner by" aid of a hinged arm 8.8, having its ends fastened to the lowermost and topmost ribs respectively. l Y- Y Vhen folded, this baby carriage will occu- -n Apy only Ya small space, and it may easily be carried by a single person, side handles (not shown) beingpreferably provided for this purpose. f Y

It is also `easily handled for folding up,`the

. parts automatically opening upand folding by pressure against the side walls after the bottoms having been folded up.

In the application of my invention on a pushcart as i-llustrated in Figs. 7 to 9, the link system is applied direct to the wheel axles, these being provided with upturned arms 88, to which the ends of the link system are connected. y.'lllhe wheel axles are fastened to usual carriage springs, carrying the cart body. `The bottom of the cart is made up of fourvboards 91, 92, 93 and 94, interconnected by hinges 95 and 96 (Fig. 9), and the outer boards 91 and 93 are connected to the sides of the cart hinges 97, 98.

` In the middle of the bottom is provided an opening V99 Ifor inserting a hand, when the cart is to be collapsed. The hinges are arranged on the under side of the bottom, so as in two hinged parts as described in the foregoing`V for the `baby carriage.

The drag arms of the cart may be arranged with hinges, so as to enable their being swung down in th'eposition indicated in broken lines in Fig. `7 in order to support the cart. .ln this position the arms abut against abutments 10,0,.provided with'hooks 101, locking them in this position. These arms are locked in their normah'upturned position by aid of spring vdetents 102. Claims. i l

In vehiclesy of the -kind adapted to be folded up in a transverse'direction, and in which a link system forms the foldable interconnection between thev opposite wheel axles, a link system comprising two pairs of crosslaid Ylinks turning about spaced pivots on members fastened between the wheel axles on opposite sides of the carriage and, linked together at the ends, said links being arranged as'double links, each link being composed of two spacedvlink parts and arranged in such manner that in the links crossing each lother the link parts of one link embrace and. guide the link parts of the other link.

2. In vehicles of .th kind adapted to be folded up in a. transverse direction, and in which a link system forms the foldable interconnection between the opposite wheel axles, a link system comprising two pairs of crosslaid links, linked 'together' at the ends, said lin-ks being arranged as double links, each link being composed-of two spaced link parts land arranged in such manner that in the links crossing each other the link parts of one link embrace and guide'the link parts of the other link, one of said links carrying a rod provided with a hook, held in locking engagement withthe link system when the vehicle is in position foruse, but automatically released which a link system forms the oldable interconnection between the opposite Wheel aXles, a link system comprising two pairs of crosslaid links, linked together at the ends, said links being arranged as double links, each link being composed of two spaced link parts and arranged in such manner that in the links crossing each other the link parts of one link embrace and guide the link parts of the other link, the inner part of the wheel axles on opposite sides of the vehicle being bent upwards and interconnected by members serving as holders for the spaced pivots of the said link system. p

In testimony whereof I have signed my name unto this specification.
